SPECIFICATION forming part of Letters Patent No. 732,767, dated July 7,1903.

Application filed April 26, 19 02.

To all whom it mayconccrn:

Be it known that I, MAX A. METZNER, a citiis tedious and leaves the edges irregularly. cleaned. The glaze of many tile are defaced in the handling, much, if not all, of the scrapings are lost, the dipper is retarded by being obliged to carefully arrange the tile in piles as he dips, and small particles of the iron or steel frequentlybecome embedded in the glaze on the top surface of the tile, causing discoloration when burned. I overcome all these ob-.

jectionsbymyinvention,which is capable with three or four hands of accomplishing as much as thirty-three or thirty-four hands could by the old method. Furthermore, the edges are cleaned uniformly, and in this connection it is important to call attention to the fact that by means of my invention just a sufficient amount of glaze in each case is left along the top of the edge to permit of the top glaze taking more firmly and uniformly around the edges. I also efiect a great economy in that by my invention all the matter removed from the tile is saved and used over again.

I attain the above objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a plan view; Fig. 2, an enlarged detail plan of brushing mechanism; Fig. 3, a portion of plan view. When lines a b are brought together with Fig. 1 they constitute a complete plan view of my apparatus. Fig.

struction of table and mode of operation at brushing-point.

Similar letters refer to similar parts th roughout the several views.

My device and suitable mechanism for operating the same are supported upon suitable framework.

My invention consists of two similar por'- tions or parts arranged at right angles to each other. For conveniencelwill first describe one part and then describe the relations of the two parts.

E is a long table in whose center and longitudinally thereof'extends a T-shaped groove M, in which travels an endless chain or belt A, (hereinafter called the carrier,) supported at each end upon wheels or pulleys C 0, one of which serves also as a driving-wheel for said carrier. The carrier-A is arranged and supported in said groove in such relation to the surface of the table E that its top does not project above the level of said surface. oarrier, as the same is less liable to stretch. This chain may be of any ordinary type used in connection with sprocket wheels with the modification of certain links at regular intervals having arms H H, with pins or lugs hh. These arms H H rest loosely upon the shoulders of theT-shaped groove, and the pins project above the surface of the table E, so as to engage therear edge of the tile when placed on the table and impel it forward along the same and between two oppositelydisposed revolving circular. brushes K K, so situated that their peripheries will bear against and clean the two opposite edges of the tile as it is passed between them. This table also acts as a support for the tile dur- The brushes KiKiare revolved inwardly upon shaftsS S at right angles to the line' of'motion of thecarrier A. The shafts S S are arranged in separate bearings N N and supplied with driving-pulleys s s. The power is transmitted so that the brushes may be run at speeds independent of the other parts of the device. These bearings and shafts are mounted upon slides P P, so that by means of adjusting-screws R R they can be made to approach or'recede from I show and prefer to use a chain for a the table are being cleaned these parts G G may be moved in toward the carrier to positions where they will support the ends of such smaller tile.

The tile is guided in its movement along the table E by small guide-rails V V, adjustable laterally on said table by means of slotted brackets v 1; and adjusting-screw w and are set far enough apart to suit the width of the tile. These guide-rails converge slightly as they approach the brushes and are slightly flexible at the ends nearest the brushes. The guides stop at the brushes, but are continued beyond the same to the table E.

The lugs or pins h h on the carrier A are arranged at intervals, according to the length of the tile edge to be dressed, as closely as will allow of one tile to be cleared out of the way of its successor by the second carrier A.

Table E, having T-shaped groove M and guide-rails V V. carrier A, having arms H H, with lugs 7L h, wheels or pulleys C G, and brushes K K are like parts in like relation to each other in the second portion of my invention, supported on suitable framework, all at right angles to the first portion.

The carrier A is driven by means of a beveled gear, as shown at 0, connected with the shaft or journal of the driving-wheel C, so that its speed is synchronous with that of carrier A. The two parts or portions are so arranged with reference to each other that as carrier A turns down over wheel 0 the tile is deposited on table E, so that the pins or lugs h h of carrier A catch the rear edge of the tile as it is received from carrier A and impel it forward along the table E and between brushes K K, which clean the opposite and remaining uncleaned edges. The tile is then deposited upon the platform or end of table 1, the carrier A turning down and around wheels 0 O and back in endless operation, as does carrier A.

The receptacles j.) 1) and 1) p receive and retain the glaze which is removed from the tile, which is preserved for remixing and futu re use. Hoods to which are connected pipes leading without the building may be afiixed to these receptacles for the purpose of drawing off by means of a blower Z any dust arising from the operation. This I do not claim as part of my invention, however.

Valuable features of the circular brushes which I use are that they clean themselves by means of their own revolutions and that the wear of the bristles is uniform, thus permitting the use of the brush until the bristles are entirely worn away. These brushes K K and K K may be driven by any suitable mechanism. In the drawings I show them driven by pulleys mounted on counter-shafts. While other forms of brushes or other wiping devices, both movable and stationary, may be used, for the reasons given I prefer the circular brushes.

The following is a brief description of the method employed in operating my invention.

The tile are dipped by hand in the liquid glaze contained in suitable receptacles Q, Q adjacent to the table E and as fast as dipped are dropped on the table. They are then caught by the lugs of the carrier A and carried between the brushes K K, which are so set as to remove the glaze from the greater portion of two opposite edges, but leaving a line of glaze along the top of such edges. The tile are then carried on a short distance and deposited automatically upon table E and are caught one'after the other by the lugs on carrier A and carried between the brushes K K, which operate upon the two uncleaned opposite edges in the same manner as brushes K K did upon the first pair of edges. The tile is then pushed onto the end of the table by the carrier A at the point where it turns down over the wheel C. The tile are removed from the end of the table by hand.

What I claim, and desire to secure by Letters Patent, is-

1. A machine for edging tile comprising one or more pairs of brushes, the members of each pair adapted to act sim ultaneously across opposite edges of a passing tile, means for adjusting said brushes, and means adapted to present the edges of different-sized tile to the action of said brushes.
